STOP-COCK.

SPECIFICATION forming part of Letters Patent No. 646,707, dated April 3, 1900.

Application filed January 24,1900. Serial No. 2,621. (No model.)

ful Improvement in Stop-Cocks, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

My invention relates to-stop-cocks such as are used inwater and gas piping, &c.; and

its object is to provide an efficient method of connecting the plug with its operating mechanism and of rendering it universally adjustable, all of which will be more fully described hereinafter and definitely set forth in the claims.

In the drawings clearly illustrating my invention, Figure 1 is'a side elevation of a cock in which my invention is shown, partly in section. Fig. 2 is a perspective of my stopbracket, and Fig. 3 is a top plan of the plug of the cock.

This invention is particularly applicable to those forms of plug-cocks in which the rotation of the plugis limited by a downwardlyprojecting dog rigid with the plug, contacting with the lugs upon the cock-body. It is desirable to have the dog separable from the plug, so that its relation thereto may be changed, as when the cock is reversed as to which end drains. Moreover, by having the dog separate the parts may be more simply cast and the plug may be turned on a lathe more easily. My invention provides a simple and efficient method of connection for the bracket carrying the dog, the plug, and the operating-lever.

Referring to the drawings, A represents a cock-body of a common form. It has a tapered bore in which is fitted the tapered turning plug B, and an upper annular flange or,

on which are radially-projecting lugs a designed to act as stops for the downwardlyprojecting dog (1, which inoperation is rigid with the plug. k

In applying my invention I provide a separate member D, which I call a stop-bracket, which is adapted to be secured to the plug and In its preferred form the stop-bracket has an angular body d from which projects an integral lateralarm d (1 which also forms the bottom of the socket 01 above, which is also of some definite shape, preferably square. 7

In assembling the parts the stop-bracket D is applied to the plug, the recess d and the boss I) coinciding, and these two parts are then locked together by a' screw G, which passes through an opening (1 in the partition d intothe plug B. The operating member or lever L is provided at its inner end with the head Z fitting the socket d, and when inserted therein is secured by a set-screw S, mounted in a boss 01 in the side of thestopbracket. The presence of the lever-headl immediately above the screw G prevents the accidental loosening of that screw, wherefore the screw S, which looks the lever, operates (through the intervention of the head Z) as a set-screw for the screw G. This makes a very simple, neat, and efficient connection between the bracket and the plug.

As will readily appear, the position of the lever L can bealtered with reference to the body by changing its position in the bracket,

other socket coinciding therewith, locking means for securing said members against lonv gitudinal detachment, a separable operative member, means for securing said member to said stop-bracket in a position-whereby it prevents the disengagement of said locking ICC means, a cock-body embracing the plug and carrying stops with which said stop-bracket is adapted to engage, substantially as specified.

2. In a cook, the combination of a cockbody, a turning plug mounted therein, said plug having on its upper face a central angular projection, a st0p-bracket having two angular sockets with a partition between them forming the bottom of each, the lower socket fitting over said projection upon the plug, a screw connecting the plug and said bracket through the said partition, an operating member having a projection fitting into the upper socket, said stop-brackethavinga projecting dog adapted to contact with stop-lugs upon the cock-body, substantially as specified.

3. In a cock, the combination of a cockbody carrying stop-lugs, a turning plug therein, said plug having centrally on its upper face an angular boss, a stop-bracket having an upper and a lower socket with a partition between them, said lower socket cooperating with said boss, a screw connecting the stopbracket with said plug through the said partition, a lever having an angular head seating in the upper socket, and retaining said socket therein, a set-screw carried by said stop-bracket having an arm carrying a projecting dog, which dog is adapted to contact with the said stop-lugs upon the cock-body, substantially as specified.

In testimony whereof I hereunto afiix my signature in the presence of two witnesses.

JOSEPH REGAR.
